Evaluation Report: P1R-15 Phase 1 Rebaseline Closeout

Date: 2026-05-04 Evaluator: Codex

Verdict

PASS for the 1-linear-static-mitc4-rebaseline sprint sequence, with documented product-level Phase 1 reference gaps.

This verdict closes the rebaseline execution path through P1R-15. It does not claim that the broader PRD Phase 1 reference target is fully complete, because R-010 and R-013 remain open in PLAN.md.

Evidence

• Rebaseline steps P1R-00 through P1R-14 were already marked complete before this evaluation.
• python scripts/validate_workspace.py passed on 2026-05-04. The command configured CMake, built fesa_core and fesa_tests, and ran CTest successfully.
• The active stored reference regression uses references/quad_02_phase1.inp and compares FESA U against references/quad_02_displacements.csv.
• The original references/quad_02.inp remains preserved as Abaqus/CAE provenance and is not treated as parser acceptance evidence for Part/Assembly/Instance.
• RF is recovered from the full vector path and covered by in-repo equilibrium/reaction tests; no Abaqus *_reactions.csv artifact is available yet.

Checklist

Item	Result	Notes
AGENTS critical rules satisfied	PASS	PLAN/PROGRESS were read before edits, architecture/numerical/reference rules were checked, and Abaqus execution was not required.
Harness contract followed	PASS	Step 15 stayed inside the allowed evaluation/documentation scope and did not implement missing solver behavior.
TDD expectations met for implementation steps	PASS	Earlier generator steps recorded failing-first or test-first validation where code was changed; Step 15 is evaluator-only.
MITC4 formulation alignment	PASS	Rebaseline steps 7 through 11 are tied to the paper-based formulation document and current drilling scale policy.
Parser subset discipline	PASS	Unsupported Abaqus/CAE provenance remains documented instead of silently expanding the Phase 1 parser subset.
Full-vector RF recovery	PASS with reference gap	Implementation path preserves full-space stiffness/load state and tests full-vector RF recovery. Abaqus RF CSV comparison remains open as R-010.
Stored displacement reference regression	PASS with PRD gap	quad_02_phase1 displacement comparison passes. The PRD target of three stored references remains open as R-013.
PLAN/PROGRESS synchronized	PASS	Step 15 updates move the active objective to post-rebaseline reference completion.

Residual Gaps

• R-010: Add Abaqus reaction-force CSV artifacts, preferably *_reactions.csv, or explicitly accept internal equilibrium tests as the Phase 1 RF verification basis until Abaqus RF output is available.
• R-013: Add enough additional small Abaqus S4 reference cases to satisfy the PRD target of three stored Phase 1 references: one single-element case, one simple multi-element plate/shell case, and one curved shell benchmark.

Closeout Decision

Mark phases/1-linear-static-mitc4-rebaseline complete. Continue project work from PLAN.md with R-010 and R-013 as the next reference-readiness tasks before claiming full PRD Phase 1 completion.
